Avego (Free)

Instead of driving four separate cars to the same huge corporate building, doesn't it make sense to save energy by all hopping in one vehicle? That's the point ofAvego, the free Android and iOS app that helps organize carpools in real-time. Users can browse rides in their area and contact that person, then the driver receives an automatic payment based on the distance traveled. You can review rides and share it with the Avego community, too.
